So I tried welding this up and it really didn't work very well. I was able to get a few spots (about 8 to 10 spot with 3 to 4 inch welds) welded and I'm hoping that seam sealer will fill in the gap. I had my welder set on the lowest setting and as soon as the wire would hit the metal it would burn a hole through it. The metal on this panel is very thin for some reason. I took a flap disc to clean off a spot and it burned a hole thru the metal as well. If it doesn't hold I guess I could weld on a piece of sheet metal about a 1/2" wide all the way around.
